Simply 50139 J-B Weld PlasticBonder- Black,25 ml

This is great stuff, the tubes are great no mess just twist off the cap and squirt it out, due to the tube design the glue is not going off between uses, sets quickly in approx. 30mins but fully cured in 24hours, then its rock hard and does not budge, great for me for all the little fixes, handy to have a tube ready to go, I also use the JB marine weld. fully recommend.

It just works. Despite some reviews stating that it is "too wet" and wrongly criticising the incredibly simple cap, this stuff is easy to mix, easy to use (when applying a little common sense) and absolutely tough as old boots. Twist and pull off the cap to open the twin tube dispenser and give the tubes a few taps to make sure there's no air trapped in either, push the plunger to squeeze out the 2 components, ensuring that they come out in equal amounts, mix well and, unless you need a really liquid material, leave for around 5 minutes, possibly even a little longer if you're using it on a vertical surface, so that it thickens up a bit. Do make sure to replace the cap the right way round, though - quite easy to do, since the component liquids are black and white. Once applied, it sets in 20 to 30 minutes (rarely the 15 minutes stated on the packaging), so you will have time to shape and smooth it as it starts to cure and might need to hold, clamp or tape a joint in place for a while. Other than that, once it has fully cured (I ended up leaving it for 24 hours, just to make sure, as it was still soft enough to indent with a fingernail, even after a couple of hours) it is both sandable and any overspill can be cut off or shaped with a sharp blade. I can only guess that those who have said it "didn't set" hadn't taken care to make sure there were equal amounts of the two components before mixing, as it is much like any 2 pack type adhesive or filler - too little hardener/activator means the product won't cure and harden. Honestly, when mixed and applied correctly, this product is so good that I have absolutely no issues with it and have ordered more for various other plastic repairs I need to do! Given how good it is, I think it's pretty good value, too.

Excellent plastic welder, managed to bond and fill losses on my soles of my shoes.

Good product at a good price. Delivery via EVRI was 10 days late. Company responded promptly to email chasing but be aware that it might not arrive when promised

Work as described. Quick drying and strong bond. Very easy to use, just squirt on hard surface mix well with provided wooden stick and apply. Wait for little and job done.

I used this to repair one area of an internal door trim card of a VW Golf, where the door mounting clips hold the trim card to the metal part of the door. I was unlucky in breaking one location on the trim card when pulling the it off the door to gain access inside. The round cheaper mounting clips will sometimes break and will need replacing, but to replace the entire door trim card is very very expensive! This plastic bonder glued the broken ABS plastic piece back to the trim card and cured rock solid and saved me a fortune. I gave it a few hours to cure to make sure it will be strong before re-assembling the door trim card. Mix it throughly and clean surfaces, apply liberally - high recommended.

Brilliant for what i required. Only issue was i lost 3/4 of it as the the plunger was stuck, then gave way and launched 3/4 of it out of the tube. Had to order a second one to complete the job i was doing

Fantastic product and does exactly what it says on the box. Spreads on easily without sagging with good adhesion.

Good quality

I bought this after doing some online research when my son accidentally broke the passenger-side mirror on my new 2026 Honda CR-V. The electronics, glass, and adjustment functions were still working perfectly, but the rotation/base area of the mirror had become loose, and I really did not want to spend around $300–$400 replacing the complete mirror assembly for one damaged section. I tried other products first without success, so I decided to give the J-B Weld Plastic Bonder a shot. I was honestly impressed. After applying it to the damaged area and holding everything in the correct position, within roughly 7 minutes the mirror already felt solid with practically no movement. For this type of repair, the bond feels extremely strong. Application is pretty straightforward, especially with the dual syringe that dispenses both components together. My main recommendation is to protect the surrounding area with painter’s tape before applying it. If you squeeze the syringe too aggressively, more product can come out than expected, and this stuff is definitely something you don’t want spreading over painted or visible surfaces. For me, this turned what could have been a several-hundred-dollar repair into a very inexpensive DIY fix. The syringe is also resealable, so I can keep the remaining product for another repair. Pros: Strong bond, sets quickly, easy to mix and apply, works well on automotive plastic, inexpensive compared with replacing the whole part, and reusable. Minor caution: Control the syringe carefully because it can dispense more adhesive than you need. Overall, this was a very impressive repair product and absolutely worth trying before replacing an expensive plastic automotive component that is otherwise still functional.

Great!!!
